Risk factors and legal proceedings

The risks Sonim Technologies names in Item 1A of its 10-K filed Apr 15, 2026: 42 risks under these headings, as written.⁷

• Risks Related to Our Business and Industry
• The future development and growth of crypto is subject to a variety of factors that are difficult to predict and evaluate. If crypto does not grow as we expect, our business, operating results, and financial condition could be adversely affected.
• In the U.S., any particular cryptocurrency’s status as a ‘security’ is subject to a high degree of uncertainty and if we have not properly characterized one or more cryptocurrencies, we might be subject to regulatory scrutiny, investigations, fines, and other penalties.
• If the SEC, a state regulator or a private litigant alleges that staking services we offer in the U.S. involve unregistered offers and sales of securities or unregistered securities broker-dealer activity in violation of the Securities Act, the Exchange Act or applicable state laws or regulations, and the courts agree with such plaintiff, we may be required to cease our staking activities and may be subject to monetary and other penalties.
• Cryptocurrency laws, regulations, and accounting standards are often difficult to interpret and are rapidly evolving in ways that are difficult to predict. Changes in these laws and regulations, or our failure to comply with them, could negatively impact cryptocurrency trading on our platform.
• A temporary or permanent blockchain “fork” could adversely affect our business.
• We currently rely on third-party service providers for certain aspects of our operations, and any interruptions in services provided by these third parties may impair our ability to support our customers.
• To become competitive and stimulate consumer demand, we must successfully manage the introduction of services and the transition and enhancement of existing services.
• We participate in a competitive industry, which may become more competitive. Competitors with greater resources and significant experience in high-volume brokerage services may be able to respond more quickly and cost-effectively than we can to new or emerging technologies and changes in customer requirements.
• We are dependent on the continued services and performance of a concentrated and limited group of senior management and other key personnel, the loss of any of whom could adversely impact our business.
• We continue to grow our business. The assumptions underlying these efforts may prove to be inaccurate, or we may fail to achieve the expected benefits from these efforts, and we may have to change our growth model in the future.
• If our products contain defects or errors, we could incur significant unexpected expenses, lose revenue, suffer damage to our brand and reputation, and be subject to liability claims.
